the issue I had with mine on a small block was they hit the intake manifold at the runners. so I trimed them with a grinder. mopar factory heads at the valve cover surface are some of the worst heads I've ever seen. get a good thick gasket and tighten them even and they will seal great. Mine came with bolts and gaskets but If I remember the bolts were too short. either way If you put them on right they are good.

It was the valve covers. The heads have perfect machined surfaces. So did the valve covers but they don't seem to have the same layout pattern as everything else and were barely sealing in places. I did have to retorque though." https://board.moparts.org/ubbthreads/ubbt...tml#Post1503062

These are the two most common issues I've seen with getting a good seal. Test fit them without gaskets to see how low and flat they fit. If you have any gaps greater than a gasket's thickness, you need to address that issue before bolting them down.
